The operation unit 11 is constituted by an input device such as a keyboard, a mouse, or a touch panel, and outputs information and the like necessary for generating a script to be operated and input to the display control unit 13. The display unit 12 is configured by an image display device such as a liquid crystal display, and displays an image for inputting information necessary for generating a scenario, an image indicating a state under test, and the like.
The display control unit 13 generates and displays an image displayed on the display unit 12, and controls the generation and display of the image according to an instruction from the control unit 14. The display control unit 13 changes the display of the display unit 12 based on the information input to the operation unit 11, or transmits the information input to the operation unit 11 to the control unit 14.
The control unit 14 displays a script creation screen on the display unit 12 via the display control unit 13 in accordance with an instruction input to the operation unit 11 to input information necessary for creating a script, or transmits information input to the operation unit 11 on the script creation screen to the script creation unit 15 to create a script. The control unit 14 transmits an instruction to the scenario processing unit 17 in accordance with the instruction input to the operation unit 11, executes a test based on the scenario stored in the storage unit 16, and displays the state during the test on the display unit 12 through the display control unit 13 based on information such as the state of the pseudo base station units 18-1, 18-2, and 18-3 and the state of communication with the mobile communication terminal 2 transmitted from the scenario processing unit 17.
The scenario generation unit 15 generates a scenario for testing the mobile communication terminal 2 based on information for generating the scenario transmitted from the control unit 14. The scenario is set with settings simulating the operation of the base station units 18-1, 18-2, and 18-3 and a communication sequence with the mobile communication terminal 2. The scenario generation unit 15 includes a transmission information generation unit 150 that generates transmission information to be transmitted from the simulation base station units 18-1, 18-2, and 18-3 based on information for generating a scenario.
The transmission information generating unit 150 generates notification information for the pseudo base station units 18-1, 18-2, and 18-3, transmission information in the position registration process, and the like, based on information for generating a script. The transmission information generating unit 150 generates notification information based on, for example, information of settings of the operation of the base station simulated by the base station simulating units 18-1, 18-2, and 18-3, which are individually set.
The storage unit 16 is composed of a hard disk device and a flash memory, and stores various scripts generated by the script generation unit 15.
The scenario processing unit 17 reads the scenario stored in the storage unit 16 by an instruction from the control unit 14, and transmits notification information to the analog base station units 18-1, 18-2, and 18-3 or executes a communication sequence with the mobile communication terminal 2 according to the scenario.
The pseudo base station unit 18-1, the pseudo base station unit 18-2, and the pseudo base station unit 18-3 transmit and receive radio signals to and from the mobile communication terminal 2 by instructions from the scenario processing unit 17.
The coupler 19 couples the radio signals transmitted from the analog base station units 18-1, 18-2, and 18-3 to transmit the radio signals to the mobile communication terminal 2. The coupler 19 transmits signals received from the mobile communication terminal 2 to the analog base station units 18-1, 18-2, and 18-3, respectively.
Here, the mobile terminal test apparatus 1 is constituted by a computer apparatus, not shown, provided with a communication module for communicating with the mobile communication terminal 2. The computer device includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk device, an input/output port, and a touch panel, which are not shown.
The ROM and the hard disk device of the computer device store a program for causing the computer device to function as the mobile terminal test apparatus 1. That is, the CPU executes the program stored in the ROM with the RAM as a work area, and the computer device functions as the mobile terminal test device 1.
In this manner, in the present embodiment, the storage unit 16 is constituted by a RAM or a hard disk device, the display control unit 13, the control unit 14, the scenario generation unit 15, and the scenario processing unit 17 are constituted by a CPU, and the analog base stations 18-1, 18-2, and 18-3 are constituted by communication modules.
In the mobile terminal test apparatus 1 having such a configuration, when the mobile communication terminal 2 is tested, a user first writes a script to be used for the test. When the user operates the operation unit 11 to select the function of scenario generation, the control unit 14 displays a scenario generation screen on the display unit 12, for example, and sets information of base stations simulated by the simulation base station units 18-1, 18-2, and 18-3, a sequence to be executed, and the like.
The user sets various information for each base station according to the test to be performed. The control unit 14 transmits the set information to the scenario generation unit 15 to generate a scenario simulating a base station. The scenario generation unit 15 generates notification information, sequence information, and the like based on the information received from the control unit 14, associates a scenario of the pseudo base station with the identification information, and stores the scenario in the storage unit 16.
When the test of carrier aggregation is performed, the scenario needs to be set in a frequency band combination corresponding to the mobile communication terminal 2. In the mobile terminal test apparatus 1 according to the present embodiment, frequency information of a cell as a component carrier is set based on a carrier aggregation band combination table of UE capability information that can be acquired from the mobile communication terminal 2.
When setting the frequency information of the cell simulated by the simulation base stations 18-1, 18-2, and 18-3 based on the information that can be acquired from the mobile communication terminal 2, the user connects the mobile terminal testing apparatus 1 and the mobile communication terminal 2 by wire, and turns on the power supply of the mobile communication terminal 2, etc., to perform location registration.
When the UE capability information is received from the mobile communication terminal 2 in the sequence of the location registration, the scenario processing unit 17 transmits the content to the control unit 14. In addition to the information at the time of location registration, the script processing unit 17 may request the mobile communication terminal 2 to transmit the UE capability information in response to a request from the control unit 14, and may transmit the received UE capability information to the control unit 14.
When the UE capability information is received from the scenario processing unit 17, the control unit 14 displays a list of band combinations that the mobile communication terminal 2 can communicate with on the display unit 12 as shown in fig. 2, for example, based on the carrier aggregation band combination table of the UE capability information.
In fig. 2, the release display unit 101 displays the 3GPP release corresponding to the mobile communication terminal 2. The classification display unit 102 displays the classification of the mobile communication terminal 2. The sub-band display unit 103 displays a frequency band corresponding to the mobile communication terminal 2. The band combination table 104 displays a list of band combinations with which the mobile communication terminal 2 can communicate. These pieces of information are information that can be acquired by the UE capability information.
In the band combination table 104, the column "CA Config" shows the band combinations of carrier aggregation. For example, "1A-8A-3A" of a circled in the figure indicates a band combination of a class of band 1, a class of band 3, and a class of band 8. In fig. 2, the band to be the primary component carrier is shown on the leftmost side. That is, the combinations of the bands of "8A-3A-1A", "3A-8A-1A", and "1A-8A-3A" are the same, but the bands of the primary component carriers are different. Regarding the frequency band to be a primary component carrier, a frequency band set to be usable in the uplink is selected in the carrier aggregation band combination table.
The column "PCell" in the band combination table 104 shows the frequency band of the cell that becomes the primary component carrier. The columns "SCell # 1", "SCell # 2", and "SCell # 3" in the band combination table 104 indicate the bands of the cells serving as the secondary component carriers.
From the band combination table 104 thus displayed, when the user clicks on the operation unit 11, for example, a mouse or the like, to select, for example, the line "1A-8A-3A" indicated by the broken line of a, and when the selection button 105 is selected, for example, by clicking on the mouse or the like, the control unit 14 sets frequency information simulating cells simulated by the base station units 18-1, 18-2, and 18-3 in the selected combination of "1A-8A-3A". As the frequency information, a value preset for each frequency band or a central value of each frequency band is set.
After that, the user operates the operation unit 11 to change the setting of the other information and the frequency information, and when the setting by the user is completed, the control unit 14 transmits the set information to the scenario generation unit 15 to generate a scenario simulating the base station.
The frequency setting process by the mobile terminal test apparatus 1 according to the present embodiment configured as described above will be described with reference to fig. 3. When the user operates the operation unit 11 to select the setting of the frequency information from the band combination corresponding to the mobile communication terminal 2, the frequency setting process described below is started.
In step S1, the control unit 14 transmits a message or the like to the mobile communication terminal 2 to acquire the UE capability information from the mobile communication terminal 2.
In step S2, the control unit 14 displays the carrier aggregation band combination table shown in fig. 2 on the display unit 12 based on the acquired UE capability information.
In step S3, the control unit 14 selects a band combination of carrier aggregation from the band combination table 104 shown in fig. 2.
In step S4, the control unit 14 sets the frequency information corresponding to the selected frequency band combination as the frequency information simulating the cell simulated by the base station units 18-1, 18-2, and 18-3.
In step S5, when the user operates the operation unit 11 to select the end of scenario setting, the control unit 14 transmits the set information to the scenario generation unit 15 to generate a scenario simulating the base station.
In the present embodiment, a list of the band combinations with which the mobile communication terminal 2 can communicate is displayed on the display unit 12, and the user selects a band combination, but the band combination may be automatically selected by the control unit 14 by a preset selection method.
In this manner, in the above embodiment, the UE capability information is acquired from the mobile communication terminal 2, the band combination of carrier aggregation is determined from the carrier aggregation band combination table of the UE capability information, and the frequency information of each cell is set in the band combination.
Thereby, the frequency information of each cell is set in the frequency band combination corresponding to the mobile communication terminal 2. Therefore, the setting of the combination of the frequency bands for carrier aggregation and the setting of the frequency information of each frequency band can be easily performed, and the test for carrier aggregation can be easily performed.
Then, a list of band combinations set in the carrier aggregation band combination table is displayed, and frequency information of each cell is set in accordance with a band of a combination selected from the list.
As a result, the combination of frequency bands corresponding to the mobile communication terminal 2 is displayed on the display unit 12, and the frequency information of each cell is set in the combination of frequency bands selected from the combination of frequency bands. Therefore, the frequency information can be set in a frequency band combination that meets the user requirements, and the test of carrier aggregation can be easily performed.
Then, a band that can be set as a primary component carrier and a band that can be set as a secondary component carrier, which are set as bands in which an uplink can be used in the carrier aggregation band combination table, are displayed in the band combination table 104.
Thereby, a frequency band that can be set as a primary component carrier is discriminated, and a frequency band that is the primary component carrier and a frequency band that is the secondary component carrier are displayed in the band combination table 104. Therefore, it is not necessary to distinguish the frequency information that can be set as a primary component carrier as a frequency band, and a test for carrier aggregation can be easily performed.
